Please specify termination and packaging codes: MSS1246-105KLC Termination:L =RoHS compliant matte tin over nickel over phos bronze. Special order: T = RoHS tin-silver-copper (95.5/4/0.5) or S = non-RoHS tin-lead (63/37). Packaging: C =7″ machine-ready reel. EIA-481 embossed plastic tape (200 parts per full reel). B =Less than full reel. In tape, but not machine ready. To have a leader and trailer added ($25 charge), use code letter C instead. D =13″ machine-ready reel. EIA-481 embossed plastic tape. Factory order only, not stocked (800 parts per full reel). 2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc using a Coilcraft SMD‑A fixture in an Agilent/HP 4263B LCR meter or equivalent. 3. DCR measured on a micro-ohmmeter and a Coilcraft CCF858 test fixture. 4. SRF measured using an Agilent/HP 8753D network analyzer and a Coilcraft SMD‑D test fixture. 5. DC current at which the inductance drops 10% (max) from its value without current. 6. Current that causes the specified temperature rise from 25°C ambient. 7. Electrical specifications at 25°C.
